Question

The number of column(s) in a column matrix are _______.

Answer 1

Answer:

A matrix must have the same number of elements in each row and the same number of elements in each column, thus an m by n matrix is a array of m rows each of n elements or equivalently n columns each with m elements. Create a matrix A with elements 1, 2, 3 in the first row and elements 4, 5, 6 in the second row.
